As long as PHD can continue to 'read' the star it won't matter much, but an OAG will lose a star more easily than a guidescope because it is putting less light onto the guide chip. In truth images captured during cloud will not be worth keeping anyway but it makes life easier if you stay locked onto the guide star so you're ready to go when it has passed. I suspect that, so long as PHD hangs onto the star, you don't need to worry. If the guiding did suffer due to lack of contrast due to cloud, so did the image at that time and you won't want to use it.
